PIPE WRENCH Filed Jan. 24, 1931 Patented Feb. 7, 1933 UNITED STATESANDREW 1B. ALLEN, OF LOGKLAND, OHIO PIPE WRENCH Application filedJanuary 24, 1931.

This invention relates to pipe and rod wrenches, and has for one of itsobjects to simplify and improve the construction and increase theefliciency and utility of devices of this character.

Another object of this invention is to pro-- vide a device of thischaracter including a stock or handle and opposing pipe or rod grippingjaws integral with the stock.

A still further object of this invention is to provide a device of thischaracter comprising an integral handle and opposing gripping jaws andwithout movable or detachable parts.

. With these and other objects in view, the invention consistssubstantially in the construction herein shown, described and claimed,and in the drawing illustrative of the preferred embodiment of theinvention in which:

Figure 1 is a side elevation of the improved implement.

Figure 2 is a top plan view of same.

Figure 3 is a bottom plan view.

Figure 4 is a transverse section on the line 44 of Fig. 1.

The improved implement comprises a stock 10 extended into a handle atone end and 0 with an inwardly curving integral jaw 11 at the other end,the inner face of the jaw be ing inwardly curved and formed with pipe orrod gripping inclined teeth 12. The stock 10 is enlarged at the junction13 of the stock 10 and jaw 11, and extending from the enlargement is anopposing jaw 14 with the face 15 confronting the curved and toothed faceof the jaw 11, and also curved but of less radius than the toothed jawas shown in Fig. 1.

smaller jaw 14 on the other side.

tween the jaws provides for gripping pipes or rods of varying sizes aswill be obvious. The transverse face of the smallerjaw 14 is greaterthan the transverse face of the toothed jaw as indicated, and theopposing 5 face is formed with spaced reduced curved ribs 16 and 17whereby the gripping force is materially increased without materiallyincreasing the weight or expense of manufacture of the implement.

Formed upon the implement at the juncture of the jaw 11 and enlargement13 is a hammer face 18 which will be found useful under manycircumstances. I

The whole implement will preferably be of 6 cast or forged steel, andbeingof a single piece may be constructed at small expense and of anyrequired size or strength, and may be adapted for use on pipes or rodsof 7 any size.

Having now described my invention, that which I claim to be new anddesire to secure by Letters Patent is:

A pipe and rod wrench comprising a handl having an inwardly curvedintegrally formed toothed jaw at one end and an integral opposing j awof less curvature than the toothed jaw and spaced therefrom, the jawsbeing flared outwardly from each other, the last-mentioned jaw having anouter circular face and having greater width than the toothed jaw andprovided with a relatively shallow curved groove located intermediatethe edges of said jaw thereby forming a pair of work- 8 engaging ribs,the side edges of the first-mentioned jaw being in planes which passthrough the work-engaging ribs.

In testimony whereof I afiix my signature.
